DRILL-FRAME.

Specification of Letters Patent.

Patented Aug. 15, 1911.

Application filed October 25, 1910. Serial No. 588,945.

To a l whom it may concern:

Be it known that I, SAMUEL J. HARRY, citizen of the United States,residing at Connellsville, in the county of Fayette and State ofPennsylvania, have invented certain new and useful Improvements inDrill- Frames, of which the following is a specification.

This invention relates to the subject of mining or excavatingoperations, and more particularly to drill frames such as are employedin the sinking of shafts.

To this end the invention contemplates a simple and practicalconstruction of drill frame, sometimes termed a shaft bar, that may beused in drilling circular, elliptical, or rectangular shafts andcomprising all possible adjustments necessary for the jackscrews thereofso that every inequality or unevenness in the shaft walls may becompensated for and the drill frame proper rigidly secured and held inits adjusted position while the drilling operations are being proceededwith.

A further object of the invention is to provide a drill frame of aminimum number of parts, while at the same time being thoroughlyreinforced and strengthened so as to be fully capable of the userequired of the same.

A special object of the invention is to provide a novel and practicalmounting of the jack-screws so as to give the same a great range ofadjustment both laterally, that is, in a direction around the frame, andlongitudinally, that is, in a direction toward and from the frame.

With these and many objects in view which will more readily appear tothose familiar with the art as the nature of the invention is betterunderstood, the same con-v i Which Figure 1 is a plan view of the drillframe constructed in accordance with the present invention. Fig. 2 is aninner edge elevation of a portion of the frame proper. Fig. 3 is anenlarged cross sectional view on the line 33 of Fig. 2. Fig. t is anenlarged detail view of a part of one of the adjustable j ack-screws.

Like references designate corresponding parts in the several views ofthe drawings.

The improved drill frame includes in its organization a circular frameproper through and about which the drilling operations are carried on.This frame proper is in circular or ring form and essentially comprisesupper and lower frame members designated generally by the referenceletters A and B in Figs. 2 and 3 of the drawing, and these frame membersare spaced apart in parallel relation to provide therebetween anadjustment guide way C designed to accommodate the inner members of thejack-screws as will be hereinafter more particularly pointed out.

The spaced apart upper and lower frame members A and B are of duplicateconstruction and each of the same preferably consists of .a continuousseries of segmental frame plates 1, which are united at their adjoiningends by means of cleat plates 2 which are riveted or bolted to thecontiguous portions of the adjoining plates and provide means forsecurely fastening the frame plates together to make a continuous framestructure.

In addition to connecting the adjoining ends of the frame plates 1, bymeans of the cleat plates 2, the said frame plates 1 have riveted orotherwise rigidly secured to their outer and inner edge portions theangle iron reinforce bands 8 which serve to materially strengthen theframe structure at the outer and inner edges thereof while at the sametime affording fastening bases for the bracing plates 4. These bracingplates 4t are arranged at the outer and inner edges of the upper andlower frame members and are riveted or bolted to the vertical flanges ofthe angle iron bands 3 as at 5. Hence, the plates t serve to rigidlybrace the frame structure at a plurality of points around the same, andalso rigidly maintain the frame members in their spaced apart relation.

A plurality of jack-screws are employed. Any desired number of thesescrews may be mounted upon the frame proper and arranged about the same.The said screws are designated in their entirety by the reference letterS and each of the same essentially consists of an outer strut member 6and an inner screw member 7. The outer stones or to do any strut member6 may be conveniently in the form of a hollow cylinder provided at itsouter end with a roughened or equivalent rest foot 9 and at its innerend with a nut element 10 in which is threaded the screw shank 11 of thescrew member 7. The said screw shank 11' of the screw member 7 isprovided at itsinner end with an operating head 12 having the sockets oropenings 13 therein to recelve a turning implement such as a lever orbar, and said operating head 12 also has a swiveled mounting as at 13upon one end portion of an adjustable carrying bolt 1.4, whichadjustably fits in the guide wayof the frame proper and has 'mountedupon its inner extremity, at the inner side of the frame proper, afastening nut 15, which serves to secure the bolt in any of its adjustedpositions. It will thus be seen that each jack-screw has a carrying bolt1'4 which may be shifted laterally or in a circular direction within theadjustment guide way C, and by means of the nut 15 may be held firmly inits adjusted position, while the operating head 12 may be easily turnedto adjust the strut member 6 either inward or outward accordmg'to thechar acter of the wall from which the frame proper is being jacked up.

If at any time it should be desired to put in timber in the shaft ortake down loose work up from the bot tom of the shaft, the drill framecan be hoisted to the proper elevation and used as a scaffold. Alsothrough the medium of any. suitable hoisting appliance, operated fromthe surface, the drill frame with its jack-screws can readily be hoistedup out of the way of the shots after the drilling is done. And in factthe improved drill frame described herein,by reason of its wide range ofadjustment and adaptability, can be utilized under any and allconditions in the sinking of a shaft and may be readily employed in ashaft or tunnel of any size.

Changes in the form, proportion, and

minor details of construction may be resorted to without departing fromthe spirit or sacrificing any of the advantages of the invention.

I claim 1.. In a drill frame of the class described, a frame propercomprising upper and lower frame members-rigidly held in a fixedrelation to each other and spaced apart to provide an interveningadjustment guideway and a plurality of jack-screws provided at theirinner ends with bolt members that are slidably and adjustably mounted insaid guideway.

2..In a drilling frame of the class described, a frame proper comprisingupper and lower frame members spaced apart to provide an interveningadjustment guide way, and a plurality of jack-screws arranged about theframe proper, each of said jack-screws comprising an inner bolt memberslidingly and adjustably mounted in said guide way, an outer strutmember having a rest foot and a nut element, and a screw member engagingsaid nut element and having a swiveled connection with said bolt.

3. In a drilling frame of the class described, a frame proper comprisingupper and lower frame members each consistmg' of a series of connectedsegmental frame plates, and angle iron reinforce bands secured to theouter and inner edge portions of said connected plates, and bracingplates secured to the upper and lower frame members to hold the latterbraced in their spaced apart relation, and a plurality of jack screwshaving carrying elements adjustably mounted between the upper and lowerframe members. 7

In testimony whereof I hereunto affix my signature in the presence oftwo witnesses.
